It just seems risky fooling around with a serious issue like fuel when I recollect all of the toasted 944's I've seen.

I think that the idea to replace the rubber line was to prevent the rubber hoses from cracking due to age and heat. Problem is that the engine torques too much and would break the hard line much sooner than the rubber line.

F18, nice setup.
